Changes in version 0.1.3 (2025-05-17)                  

  - Fixed the description file: NeedsCompilation is now set to "no".

  - Updated the reference to the main article.

  - Fixed the ptsr.link function. Now both derivatives corresponding to
    the identity link return a vector of ones with the same size of the
    function's argument.

                 Changes in version 0.1.2 (2022-02-08)                  

  - Fixed an error: Inside the function predict.ptsr, the argument xreg
    was not being passed to the internal function ".ptsr.predict.".

  - Fixed an error: in the internal function ".ptsr.predict.", the MA
    lags were incorrectly specified. This was causing an error in the
    prediction for some models.

  - Release date: 	2022-02-08

                 Changes in version 0.1.1 (2022-02-01)                  

  - Added check for infinity and NAN in the log-likelihood function.
    Now, "Inf" and "NAN" are replaced by 2.2e+10 and "-Inf" is replaced
    by -2.2e+10 avoiding issues with the optim function.

  - Added an internal function to calculate the numerical hessian. This
    function is only used if the inversion of the output of
    numDeriv::hessian fails.
